ATTORNEY Patented Nov. 26, 19 29 ETEQ STATES ELI E. SAGEB, or SEATTLE, wasnrneron MIXING TUBE Application filed October 19, 1828. Serial No. 313,614.

My invention relates to certain new and useful improvements in mixing tubes especially designed and adapted for use with carbonators of the type disclosed in Letters Patent No. 1,559,465, issued to me October 27, 1925. Such caroonating machine employs a mixing tube through which the carbonated water is withdrawn and during the passage through the mixing tube the carbonic acid gas is thoroughly mixed with the water.

The present invention has for its object to reduce the cost of manufacture both from the material and labor standpoints of the type of mixing tube disclosed in my patent above 5 referred to and to that end the present invention comprises a mixing tube composed of end units and a series of intermediate units, the intermediate units all being alike and when assembled with the end units, consti- 2Q tute an outer wall or shell, a central series of aligning hubs and perforated disk portions uniting the hubs and rims of the units into an integral structure, provision also being made to secure the several units in alignment along a common axis with their rim portions in contact with one another to efiect a substantial sealing or closure between the adjacent surfaces of the rim sections in order to produce in the assembled device the required outer shell or casing.

In its more detail nature the invention also includes those novel features of construction, combination and arragement of parts, all of which will be first fully described, then be particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Figure 1 is an elevation, parts being broken away showing a carbonating apparatus employing my invention.

Figure 2 is a vertical longitudinal section of one of my mixing tubes assembled.

Figure 3 is a detail perspective view of one of the intermediate units.

In the drawings, in which like numerals of reference indicate like parts in all of the figures, A represents the tank of the carbonating machine which may be of the usual construction and as the other parts of the carbonating machine do not constitute my present invention further description will be limited to the mixing tube shown.

Referring now particularly to Figures 2 and 3, it will be seen that 1 designates the rim portions of the intermediate sections 0 which are united to central hub portions 2 by perforated webs 8. Preferably the rim portions 1 of the several sections have one edge grooved as at f and the other tongued as at 5 so that when the several sections are assemlgled the rims will have a tongue and groove The upper end section 6 is provided with a neck 7 that is threaded, or has other provision for coupling it to the supporting bod or to the duct which delivers the carbonate: water from the mixing tube. The upper end section 6 is also provided with a hub 9 that is threaded to receive the threaded end of the securing bolt 11, the hub 9 being connected with the outer wall or shell portion of the section 6 by meansof spokes 10. The end of the rim portion of the section 6 which engages the adjacent rim portion 1 is also preferably tongued as 8 to fit the groove 4 of that section.

The lower section 12 need only be provided with the groove f and it may be made slightly deeper, than the intermediate sections so as to project beyond the head of the screw bolt 11 and thus afford it some protection.

In assembling, the several units are placed with their rims edge to edge and the screw bolt 11 passed through the several hubs 2 and screwed into the hub 9. Should leakage occur between the several units the joints can be ground together by simply turning one unit on the axis of the bolt 11 until the engaging surfaces fit properly. i

It is intended that the several units shall be die cast in order to reduce the cost ofmanufacture and when die cast it will ordinarily: not be necessary to grind the surfaces land 5.

If desired, when the parts have been assembled the joints between the adjacent rim sections may be further rendered watertight by suitable solder or otherwise. However, for ordinary purposes it is thought that the soldering operation will be unnecessary.

It will be seen that with the present con-I struction of mixing tube the time required for assembling can be materially cut down and thus reduce the labor cost, and the difiicult of fitting a series of thin metal disks into a tu e or pipe, as in my patent above mentioned, is avoided.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be clear to those skilled in the art to which it appertains.

What I claim is:

1. A mixing tube comprising a series of sections each consisting of an outer rim, a hub and a perforated web joining the rim and hub, and means connecting said sections together rim to rim and hub to hub along a common axis whereby said rims when assembled will constitute an outer shell.

2. A mixing tube comprising end and in termediate sections each including an outer rim and an inner hub, the intermediate sections including a perforated web connecting rim and hub, said hubs each having a bolt hole, a bolt passing through said bolt holes to retain said sections in assembled relation with their axes in alignment, their hubs together and their rims located in edge to edge contact to constitute an outer Wall or casing.

3. A mixing tube comprising end and intermediate sections each including an outer rim and an inner hub, the intermediate sections including a. perforated web connecting rim and hub, said hubs each having a bolt hole, a bolt passing through said bolt holes to retain said sections in assembled relation with their axes in alignment and their rims located in edge to edge contact to constitute an outer wall or casing, the hubs of the several sections adapted to contact one another, said rims having one of their contacting faces annularly grooved and the opposite contacting faces correspondingly tongued for the purposes specified.

4;. A mixing tube having end and intermediate sections, each including an outer rim portion, an inner hub, and means connecting rim and hub, the connecting means of the intermediate sections comprising webs perforated at invervals, said hubs each having a bolt hole, a bolt passing through said bolt holes to secure said sections together along a common axis with the rims of the several sec tions in edge to edge contact, thereby constituting an outer 'shellior casing, one end section having a neck with means for its connection to another body.
